Sana, the innocent beauty I met at cram school, moves to Tokyo for university while I remain behind to retake my entrance exams. She tells me she will attend an adult tennis club’s welcome party, but she cannot handle alcohol and I worry about her drinking with strange men. A reassuring video instead shows loud party boys touching her while she smiles and makes no effort to stop them. I cannot shake the sickening thought that she might stay the night, become aroused while drunk, let them grope her breasts, and moan while riding a shallow campus playboy’s cock—even though I desperately tell myself it could never happen.
